Hatoyama Hall ( 鳩山会館 )

Hatoyama Hall (鳩山会館 Hatoyama Kaikan), also known as the Otowa Palace (音羽御殿), is a Western-style residence in Bunkyō, Tokyo built in 1924 by Iichirō Hatoyama, and it was here that he helped form the present Liberal Democratic Party. The house and gardens are in the process of evolving into a museum commemorating the Hatoyama family's contributions to politics and education in Japan.
